I like this list a lot! Grixis is one of my favorite color combos. The interaction between Chandra and Into the Core is boss. Plus she interacts favorably with Snapcaster Mage. Have you thought of Chandra's Phoenix for this list? I might just be thinking janky red but..You have a lot of reliable ways to bring it back. I heard Bloodghast/Vengevine were good.....something to think about. Also Army of the Damned. DO IT.

Nate post those compliments I need a good a laugh. The deck seems slow. Which is fine it is a control deck. However I see this having a hard time with quick burn or hard hitting agro. I could be wrong. How is the playtesting going with this deck.

So far in playtesting, all results have been positive, aggro isn't a huge deal because of arc trail - slagstorm - chandra and liliana all team up well to bring it down.

anyways looking forward to some play testing with the deck more. need to test it vs. wolf run green, t-steel, and rdw. those are the next 3 decks of playtesting imo. if i can get all those match ups good than i'll bring it vs. solar flare lol.
